ROLLER WINDOW-SCREEN.

Specification of Letters Patent.

Patented Oct. 19, 1920.

Application filed June 8, 1920. Serial No. 387,448. L

To all whom it may concern:

Be it known that I New H. NELSON, a citizen of the United States, and a resident of Spencer, in the county of Clay and State of Iowa, have invented a certain new and useful Roller Window-Screen, of which the following is a specification.

The object of my invention is to provide a roller window screen of simple, durable and inexpensive construction.

A further object is to provide in a device of the kind mentioned, a screen mounted upon a roller and provided with a novel means for mounting the roller, whereby the roller may be supported on the window casing.

A further object is to provide in such a device suitable means for guiding and sup porting the side edges of the screen when the screen is withdrawn, the parts being so arranged that they will be held in a taut position, when it is withdrawn and placed over the opening in the window.

A further object is to provide a spring clip device fixed to the window casing near the sill for locking the screen in its withdrawn position.

Still a further object is to provide a spring actuated roller adapted to roll the screen into a minimum amount of space,

. when the screen is in its inoperative position.

A further object is to provide reinforcing clips adjacent to each of the edges of the screen, the clips also serving as a medium for holding the screen within its guides.

Still another object is to provide such a device with means for adjusting the screen, so that it may be placed upon windows varying slightly, due to inaccuracy or shrinkage in the caslng.

A further object is to provide in such a device, a means whereby the tension of the spring may be varied and a mechanism for holding the spring in any of its various positions.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims,

and illustrated in the accompanying drawin s, in which:

igure 1 shows an outside elevation of a window equipped with my roller screen.

Fig. 2 shows a central sectional view taken on the line 2-2 of ig. 1.

Fig. 3 shows a detailed, side View of the resilient stop device.

Fig. 4 shows a detailed, sectional view illustrating the reinforcing clips placed adjacent to each side of the screen.

Fig. 5 shows a central, sectional view taken on line 5--5 of Fig. 2, illustrating the adjustable casing for holding the screen roller.

Fig. 6 shows a front, detailed view of'a corner of the window screen, parts being broken away to better illustrate the construction.

Fig. 7 shows a sectional view taken on the line 7-7 of Fig. 1, illustrating the looking device for holding the spring in its tightened position; and

Fig. 8 shows a detailed, sectional view taken on the line 8-8 of Fig. 1.

In the accompanying drawings, I- have used the reference numeral 10 to indicate generally the upright side members forming part of the window casing or j amb; the reference numeral 11 indicates the upper member thereof, while the sill is indicated by the reference numeral 12.

My device consists of a casing 13, which is provided with an open inner side adjacent to the window casing. The casing 13 is provided with an upwardly extending flange member 14, which has its edge slightly bent inwardly at 15. The inner edge 15 is slightly sharpened, so that it may project slightly into the upper member 11 of the window casing. This will prevent any water from leaking into the interior of the casing 13.

The casing 13 is held in position by means of the screws 16, which extend through the flange 14 and into the upper member 11 0f the window casing. The casing 13 has slidably mounted upon one end of it, a cap or closure member 17. The closure member 17 is provided with an upwardly extend-. ing flange 18, which is similar to the flange 14 of the casing 13.

An elongated slot 19 is provided in the flange 18 through which is adapted to be received a screw 20*.

By providing the slot 19 and the screw 20 it will be seen that the closure member 17 may be slid longitudinally for a short distance on the casing 13.

I provide the adjustable cover 17 so that I am able to overcome any discrepancies or inaccuracies in the manufacture of the window casing.

It will also be understood that the upright members 10 of the window casings may vary a fraction of an inch due to climatic conditions.

By making the closure member 17 adjustable, I am able to install my device readily and quickly without any great amount of inconvenience.

Mounted within the casing 13 is a pair of transverse partition members 20, which are provided with the bearings 21. Rotatably mounted within the bearings 21 is the roller 22, which is provided with a slot 23, which extends between the adjacent surfaces of the partition members 20.

The roller 22 is provided with an end member 24. Mounted within the roller 22 is the spring 25, which has an end 26 extended through the end member 24 of the roller 22. The free end of the roller 22 is open substantially as illustrated in Fig. 5 of the drawings.

The free end of the spring 25 is fixed to a rod or squared shaft 27. The cap or cover member 17, which is adjustable is provided with-an opening 28, through which is extended the shaft 27. Fixed on the outside of the casing 17 adjacent to the shaft 27 is the forked member 29, which is pivoted to the closure member 17 by means of the pivot 30. The forked member 29 is adapted to receive the squared shaft 27, thus preventing any rotation of it.

It will be seen from the construction of the parts just described that the spring 25 has one end anchored to the revoluble roller, and has its other end anchored to the squared shaft 27.

It will also be noted that the roller 22 is substantially shorter than the combined length of the casing 13 and the cover member 17, thus permitting the cover member 17 to be slid longitudinally on the casing 13;

Fixed to the upright window casing members 10 are the spaced guide members 31, which are fastened to the upright members 10 by means of the screws 32. Each of the guide members 31 comprises a flange 33and a pair of jaw members 34 and 35. The jaw members at their inner ends are slightly Spaced apart. This is illustrated in Fig. 8 of the drawings.

Received within the slot 23 of the roller 22 is one end of the screen 36. The end of the screen 36 is inserted in the slot and is then bent over at 37, in order to form a lock or means for holding the screen onto the roller 22. The screen is preferably of the width between the two partition members 20.

Adjacent to each edge of the screen 36 arethe combined reinforcing and guide clips 38. Each of the combined reinforcing and guide clips 38 are extended through the screen 36 and are then bent over in order to form a substantial link, as illustrated in Fig. 4 of the drawings.

It will also be noted that there is a slight space between the combined reinforcing and guide clips 38, which serves as a hinge or provides a resilient portion between each of the links, so that the screen may be rolled onto the roller Without any difliculty.

The portion of the screen having the combined reinforcing and guide clips 38 thereon is received within the spaced guide members 31 and held between the jaws 34 and 35. The clips 38 form a substantially wider portion than the opening between the jaws 34 and 35 of the guides 31, thus preventing the screen from becoming loosened or passing out of the guides 31. This holds the screen k3:3 tightly between the spaced guide memers.

At the lower end of the screen 36, I have provided a combined binder and handle portion 39, which is preferably made of sheet metal and is bent upon itself so as to engage the lower end of the screen 36 and to have a rearwardly extending portion 40, j

which is used as ahandle for raising or lowering the screen.

Each end of the combined binder and handle 39 is provided with a loop 41, as illustrated in Figs. 6 and 8 of the drawings. The loops 41 are received within the guides 31 and are adapted to slide therein.

The partition members 20, which are mounted within the casing 13 extend inwardly slightly beyond the edge of the easing 13. The guides 31 have their upper ends set adjacent to the partition members 20.

It will thus be seen that when the screen is rolled up or held in its inoperative position, that the loops 41 will strike against the partition members 20 and thus limit the upward movement of the screen 36. This will also hold the screen and the loops 41 within the guides 31 all of the time.

Secured to the edge of the window frame and projecting into the path of the ends of the combined handle 40 are the resilient stop devices 42, which are fixed to the frame 10 by means of the screws 43. The lower end of each of the resilient stopping devices is provided with a notch 44, which engages with the handle portion 40 ofthe combined binder and handle member 39. As soon as the handle 40 has passed below the upper edge of the notch 44, the resilient stopping devices will spring to position where the edge of the handle member 40 will be re ceived within the notch 44. When the screen is in this position, it will be seen that I haveprovided a complete screened closure device.

When it is desired to release the window, all that isnecessary is to engage the resilient stop device 42 and move their lower ends toward the upright casing members 10, which will cause the notches 4:4 to disengage from the handle member 40. The spring,

.which has been Wound or tightened when the screen is moved to its operative position, will be caused to become unwound, thus rolling the screen-onto the roller 22. When the screen is rolled onto the roller 22, it will be practically all received within the casing 13, which forms a compartment for holding the screen against the action of winter weather, thus preventing corrosion'and destruction of the screen.

The casing 13 is designed to be permanently fixed to the window frame and to contain the screen during the winter months when a screen is not necessary, yet when it is desired to use the screen, the operator may instantly draw the screen downward and lock it in position, and the screen is then installed for use in the summer months.

If it is ever desired to remove the roller 22, the screen is withdrawn from the slot 23, and then by removing the closure or cap member 17 from over the end of the casing 13, the roller '22 may be pulled or slid out of its bearings 21.

In this way, it will be seen that the spring may be changed or a new one installed or any of the other parts may be installed without the necessity of removing the entire casing member 13 from the window casing member.

he advantage of my device resides in the fact that I am able to so construct the casing member that it may be used upon windows of varying sizes and that I am able to completely pack the screen 36 into the casing 13 in winter.

Another advantage of my device is that I am able to quickly remove the screen from the window, when it is desired to wash the outside of the windows.

When the screen has been pulled out its full length and is fastened down by means of the resilient stop devices 42, the tension of the spring 25 will tend to pull the screen upwardly, which will cause the screen to be tightly rawn between its upper and lower edges, while the guides 31 and the combined reinforcing and guide clips 38 will cause the screen to be drawn tightly between its side edges, thus forming a device which will cause the screen to always be in its taut position.

Some changes may be made in the construction and arrangement of my improved screen structure without departing from the real purpose and spirit of my invention, and it is my intention to cover by my claims any modified" forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
